BIRMINGHAM, Alabama -- Construction on the second phase of Birmingham-Shuttlesworth International Airport's terminal modernization project is about 90 percent complete, airport officials said Monday.

The project is moving toward a June completion date said Jeff Hart with Brasfield & Gorrie, the firm managing the project in a joint venture with Bloc Global Services Group.

Concessions vendors and airlines who will occupy the new concourse could begin moving in toward late June, Hart told Birmingham Airport Authority board members.

The Concourse C renovations are the second and final phase of the $201.6 million project which began in 2011 to upgrade the terminal to post-Sept. 11 security standards and expand traveler conveniences. The first phase -- Concourses A and B -- opened in March 2013.

In Concourse C, concessions will be available in the pre-security area. Some vendors already are constructing their spaces within the terminal's new wing, Hart said.

In the rest of the renovated building, roofing and exterior paneling are complete. Construction continues on the parking deck elevator nearest the new concourse. Glass panels soon will be added to close in the elevator shaft.

Paving also is under way on the apron, or the area surrounding the new concourse where planes park for boarding.

Interior work also continues. Carpeting, tile flooring, restrooms, airport authority office spaces and a community meeting room on the second level are being finished.

Crews gradually will begin turning on some of the new terminal's permanent lighting, Hart said.

Contracts have been paid out on 88 percent of the project's budget said Tom Wesley, airport authority project manager.
